What skin condition is characterized by excessive hair growth in unexpected areas?

The condition characterized by excessive hair growth in unexpected areas is known as hirsutism. This condition typically affects women and is characterized by the growth of coarse, dark hair in areas where men usually grow hair, such as the face, chest, and back. Hirsutism is often associated with hormonal imbalances, particularly elevated levels of androgens, or male hormones.

While other conditions listed have distinct characteristics—such as dermatitis, which involves inflammation of the skin; alopecia, which refers to hair loss; and psoriasis, which is a chronic skin condition characterized by red, scaly patches—none specifically relates to the excessive hair growth described in the question. Understanding hirsutism and its causes can aid professionals in recognizing and addressing this condition effectively within a cosmetology context.
